Hi,
We are using AT%XVBAT command to get battery voltage and detect low battery.
We facing issue in CFUN=20 mode, sometimes AT%XVBAT is returning latest voltage and sometimes...
Hi there,
I would like to add some extra data to mesh-nodes, when not provisioned -- with ble_advdata_manuf_data_t usage. What is the best way to do it and where?
And...
I have a simple OnOff client server running on Zephyr. I'm developing on macOS and platformio.The nodes are self configured. If I restart the client it cannot reconnect to...

Hello. I'm using the NUS BLE service to send ADC sensor data. I am having the SAADC callback function call ble_nus_data_send() to send raw samples. I have set the min and...
I need to measure full power consumption of nrf52, on PCA10040 from... a 5V source (because including some other 5V devices). I measure it from 5V pin and not usb plug. I...
Hi,
as I know from the mesh spec, the number of elements cannot change after a device was provisioned. Nordic even went so far as to define the number of elements during...
Hi, how to measure RSSI in OpenThread? I have 2 nodes, what is correct state that I have to assign to each node to do transmit/receive test, is it leader and router? or router...
Hello,
We're thinking of powering external sensors through GPIO pins configured as high-drive. The sensors themselves consume only a few milliamps at most, which is easily...
Hi,
I would like to control a piezo driver using GPIO pin on nRF52840 DK.
I've read posts about this kind of application. But still confused about how to set up PWM...
Hello again Nordic Pro's,
I have a mildly modiffied version of ble_app_uart_c that compiles and runs fine on an NRF52-DK board. I am now trying to use the same code on a...
